PS-InSAR技术的昆明地表沉降特征提取与分析
|
摘要
针对昆明2015—2017年可能存在的地表沉降问题,该文通过永久性散射体干涉技术和GIS方法,利用34景Sentinel-1时序降轨数据,揭示了昆明市城区地表沉降的空间分布特点和变化规律,并从地质、水文、人为等方面分析了成因和影响因素。研究结果发现,昆明市城区地表整体存在形变,平均速率在±10mm/a之间。以渔户村、广卫村和洪家村为中心形成了3个面积较大的沉降带,分布在靠近滇池北岸的南市区,而西北方向的普吉片区和环城西路附近的棕树营片区是本次研究中发现的两个新沉降点。
Aiming at some possible up-and-down situations from 2015 to 2017,this paper revealed the ground deformation distribution characteristics and change rules in Kunming city with 34 descending images from Sentinel-1,by means of PS-InSAR and some GIS techniques.Meanwhile,in terms of geology,hydrology and human factors,the causes and influence factors of subsidence were summarized and analyzed.It showed that there was an extensive deformation in Kunming city,whose average velocity among±10 mm/a.Besides the north of Dianchi Lake,taking Yuhu,Guangwei and Hongjia as centers,3 subsidence zones with big areas and rapid subsidence rates had been discovered.Puji in northwest and Zongshuying around west ring road are two new discoveries in this paper.
